When some folks first hear of Loop or biosolids they have questions about testing and safety. These questions are reasonable given the stigma of disease and pollution associated with untreated human waste. Regular testing ensures high product quality, while decades of university research with renowned university research partners have answered important questions such as: what’s in biosolids? How do biosolids benefit plants and the environment? Are they safe to use? 

Thanks to thousands of scientific studies, the benefits of biosolids as a fertilizer and soil builder has been repeatedly demonstrated. Not only that, but many of these studies also help define best management practices, introduce improved treatment technologies, and provide scientific foundation for regulations. Science has also unearthed a trove of biosolids benefits.
